iCloud integration: photo, document sync, and re-download any purchased content at any time (iTunes Match is coming later this month)

Newsstand: automatically updates magazines and newspapers overnight so you’ll have it in the morning during the commute

Reminders: great to do list with iCal, Outlook, and iCloud support

Twitter: deep twitter integration

Camera: grid lines, pinch-to-zoom gestures, and single-tap focus and exposure locks. Use volume-up button to take a picture. ObamaPacman pro tip: use the virtual button on the display so you have less camera shake. Use hardware button if you cannot see the display (such as taking photo with friends)

Photos: crop, rotate, enhance, and remove red-eye in app. Sync with iCloud and your Mac, PC, or other iOS devices.
